SPECEFICATION forming part of Letters Patent No. 623,306, dated April 18, 1899.

Application filed December 27, 1897. Serial No. 663,536. (No model.)

To (all. wit/mt it may concern:

lie it known that we, PETER A. COUPALand \VILLIAM GORDON, of Boston, in the county of Suffolk and State of .llassachusetts, have invented certain new and useful Improvements in lnnenSole Machines, of which the following is a specification.

This invention relates to the manufacture of inner soles for boots and shoes, the sole having its margin reduced in thickness and a lip turned upwardly from one side of the sole, the said lip being-formed by slitting the edge of the sole, thereby forming a out which is parallel with the sides of the sole and dividing said edge into two parts, one of which is afterward turned upwardly from the plane of the sole and set reform a lip standing up-.

ward from the sole.

Our invention has for its object to provide improved means for forming said lip; and to this end the invention consists in the impror'ements which we will now proceed to describe and claim.

Of the accompanying drawings, forminga part of this specification, Figure 1 represents a top plan' view and partial horizontal section showing the principal parts of amachine embodying our invention. Fig. 2 represents a section on line 2 2 of Fig. 1, looking toward the left. Fig. 3 represents a View similar to a portion of Fig. 2, the slitting and trimming knives being omitted. Fig. 4 represents a section on line 4: 4 of Fig. 1. Fig. 5 represents a perspective view of the lip-setting hammer. Fig. 6 represents in separate views the sole-edgeslittingandlip-trimmingknives. Fig. 7 represents aperspective view showing said knives connected and showing a portion of an inner sole. v

The same letters of reference indicate the same parts in all the figures. 1

In the drawings, a represents a sole supporting and feeding bed, which is preferably a disk having a beveled upper face a and mounted on a shaft 1), which is rotated by any suitable means, so that an inner sole 0, resting on the face a, as indicated in Figs. 1 and 2, will be moved in the direction indicated by the arrow in Fig. 1.

(1 represents a fixed gage which projects over the sole-support a, in position to bear on the margin of the sole 0 and guide the latter.

c represents a SOleedge-sliLting knife the shank e of which is secured to a suitable fixed support f, which forms a part of the supporting-frame of the machine. The knife 6 has a cutting edge c which projects over the support and is formed to make a slit or incision 0' in the edge of the sole 0, said incision being parallel with the upper and lower surfaces of the sole; At the rear of the cutting edge e is a raised boss 8 formed to bend outwardly from the plane of the sole the lip 0 which constitutes one of the parts into which the edge of the sole is divided by the slitting knife. The outer surface of this raised boss 6 is rounded, as shown in Figs. 6 and 7, to properly turn the lip c of the sole.

9 representsaliptrimmingknife the shank g of which is affixed, with the shank e, to the supportf, the said shanks being preferably secured by means of screws 71 h,passing through slots h in the knife-shanks,said slots enabling the slitting and trimming knives to be adjusted longitudinally. The trimming-knife 75 g is arranged to trim off the outer edge of the lip c to give said lip the proper width before it is turned upwardly by the boss 6 'i represents a support for the upwardlyturned lip. Said supportis preferably a disk mounted on a shaft 2" (shown in dotted lines in Figs. 1 and 2) and journaled in suitable bearings (not shown) in the frame of the machine, the periphery of the disk being arranged to bear on. the upper surface of the sole 0, while one side of the disk is arranged to bear against one side of the upwardlyturned lip, as shown in Figs. 2 and 3. The shaft t" may be positively rotated, so that the disk i will assist the sole-support a in feeding '90 the sole in the direction indicated, the periphery of the disk being preferably milled or roughened. The side of the disk which bears against the lip c is preferably recessed to form an inclined annular face t (See Figs. 1, 2, and

j represents a lip-setting device arranged to cooperate with'the lip-support t' in setting the lip c in such manner as to make permanent the form shown in Fig. The said setting 10o device is preferably a hammer, to which a reciprocating motion is imparted toward and from the support 2', the said hammer having a facej, which is substantially parallel with the face 2' of the support i. The shank j of the hammeris movable in a fixed guide formed in the supportf and is provided atits rear end with a slotj which receives a pink, eccentrically mounted on a shaft k, which is rotated in fixed bearings by any suitable means, such as a belt applied to a pulley k affixed to said shaft. The rotation of the shaft it causes the pin k to rapidly reciprocate the hammer and cause its face j to strike the lip c and cooperate with the support 1' in permanently setting said lip.

It will be seen that the operations of slitting the edge of the sole and raising and setting the lip c are performed simultaneously, so that the operation of making an inner sole of the character shown and described is quickly and satisfactorily performed. We do not limit ourselves to the described details of mechanism and may variously modify the same. Any suitable setting device adapted to cooperate with the lip-support may be used instead of the hammer j.

We claim 1. A machine of the character specified, comprising a rotary sole-support, a rotary wheelt' adjacent thereto, formed and arranged to serve as a'feed-wheel and as a lip-support;

a sole-edge-slitting knife, and a reciprocating lip setting hammer arranged to cooperate with the wheel 2 in forming a lip on an inner sole.

2. A machine of the character specified, comprising a sole-support, a lip-support adjacent thereto, a lip-setting device arranged to cooperate with the lip-support, and a lip raising device independent of the setting device, adapted to turn a portion of a sole upwardly and interpose it between the said lipsupport and lip-setting device.

3. A machine of the character specified, comprising a sole-support, a lip-support adjacent thereto, a knife arranged to slit the margin of a sole, thereby partially forming a lip, a lip-turning device arranged to raise the lip from the plane of the sole, and a lip-setting device arranged to cooperate with the lipsupport in setting the raised lip.

4. A machine of the character specified, comprising a sole-support, a sole-edge-slitting knife projecting over the support, a lip turning or raising device, and means for setting the lip cut by the action of the knife and causing said lip to overhang the face of the sole, said means comprising a beveled or inclined lip-support and a reciprocating hammer having a correspondingly beveled or inclined acting face.

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witn esses, this 21st day of December, A. D. 1897.
